On Christmas Day, 500 planes are grounded at Denver International due to extremely inclement weather due to a storm. To fly, each plane must have less than 0.25 inches of snow covering the body. a. Given a normal distribution with a mean = 0.41 inches and a standard deviation o-0.07 inches, what is the probability that a randomly selected plane will have less than 0.25 inches of snow on their body? b. What is the estimated probability that 12 or more planes will be cleared to fly after the storm?
